I know the blue side purple side issue has been around for a while. I also know that there is a lot of data to back up the unbalance between purple side and blue side. I personally have no problems playing on purple side. The biggest issue, and it is really more of a non-issue, is having to decide how my jungle route is going to change depending on the side that i'm playing on. I moved into league after a fair bit of experience playing real time strategy games such as Warcraft and Empire Earth. So I can not recall ever having depended on using a locked screen as my primary mode. This I think has translated into me not suffering any sever game play issues while on purple side, none that I notice anyways. But in the same breath, one of my closest friends despises purple side. Honestly he is a better player than I am but he also plays with a locked screen. He says that the camera perspective makes it harder to harass and keep an eye out for trades. So all in all I think playing on purple side just requires a slightly different skill set and the ability to adjust. Which does support the argument that the sides are not fair.
Also as a side note, I have been playing on purple side so much recently due to a nasty loss streak which in turn has caused me to pick up that purple side does have some advantages. I personally feel that purple side gives the jungler a slight advantage. My two favorite Junglers are Nocturne and Zac. both of which have a method of being able to jump walls which I find makes ganks on the bottom lane a whole heck of a lot easier. I also tend to be able to gank top lane much earlier in the game which has a much higher potential to snowball. The easier access to the dragon pit also makes dragon control noticeably easier for my team as well.
Disclaimer: these are all just my personal opinions. They do not change the data that has shown over and over again that purple side does have an advantage. Unless riot decides to make some significant changes to the map, which i will be all for, i think the best that can be done is to put in the little bit of effort to adapt and make the most of purple side. It will require a little bit more effort but in the end it will make you a better player. No one can deny that the ability to adapt is important in any League of Legends match.
